Magical magnetron sputtering technology: giving new life to PI and PET tungsten plated films

Introduction: In today's industrial field, surface coating technology is constantly innovating, among whichApplied FilmIt has received widespread attention for its high efficiency, high quality, and ease of control. This article will explore how to use magnetron sputtering technology to coat tungsten film on polyimide (PI) and polyester (PET) substrates, significantly improving their fatigue strength, wear resistance, and heat resistance.

Characteristics of PI and PET substrates

PI and PET, as common engineering plastics, have excellent mechanical properties, high temperature resistance, chemical stability, and electrical insulation, and are widely used in the fields of electronics, automotive, and aerospace. However, their surface properties need to be improved, and issues such as easy water absorption and lack of high temperature resistance limit their wider application.

Applied Film

Magnetron sputtering technology is a method of sputtering materials (target materials) onto the surface of a substrate, and the sputtering process is controlled by an external magnetic field to prepare uniform and dense thin films. This technology can be carried out under vacuum conditions, thus effectively avoiding issues such as oxidation and obtaining high-quality thin films.

Advantages of tungsten plating film

Tungsten is a metal with high melting point, high hardness, and good chemical stability. Coating with tungsten film can improve the surface hardness and wear resistance of the substrate, while also possessing good conductivity and oxidation resistance. Coating tungsten film on the surface of PI and PET can improve their heat resistance, corrosion resistance, and mechanical properties, and expand their application fields.

Technical Challenges and Solutions

When coating tungsten film on PI and PET substrates, there are some challenges, such as surface roughness of the substrate and adhesion of the hanging film. To address these challenges, optimization of sputtering process parameters, improvement of substrate surface treatment quality, and enhancement of target material purity can be employed.

Application prospects and prospects

By using magnetron sputtering technology to coat PI and PET substrates with tungsten film, they can be more widely used in electronic devices, optical components, medical equipment and other fields. In the future, with the continuous improvement of technology and the expansion of applications, this technology will provide more possibilities for surface functionalization of materials, promoting the development of materials science.
